Definitions

  • the network controls the mobility of a mobile communication unit (or user equipment (UE) in 3GPP parlance) that is in a connected mode (or to be precise in 3GPP terms in an RRC_CONNECTED state). For example, the network decides with which cell the UE maintains a radio connection (also referred to as the serving cell). The network applies the handover procedure to move the UE from one cell, namely the serving cell, to another cell, referred to as the target cell. The network decides the cell, as well as the Radio Access Technology (RAT) in some circumstance, that the UE should connect to typically based on radio quality.
  • 3GPP 3rd Generation Partnership Project
  • FIG. 1 illustrates an example of a typical overall handover procedure 100 for a UE 105. More specifically FIG. 1 illustrates an Intra-MME (Mobility Management Entity)/Serving Gateway handover as defined in the 3GPP Technical Specification (TS) 36.300.
  • Intra-MME Mobility Management Entity
  • TS Technical Specification
  • the measurement configuration expressed by way of a 'delta' compared to the configuration used in the source cell (the delta indicating configuration changes, as opposed to complete configuration information, in order to reduce the size of the message);
  • the signalling used upon handover applies delta signalling for the various parameters, or fields in 3GPP parlance, whereby the radio access network (Evolved Universal Terrestrial Radio Access Network ? EUTRAN in the case of 3GPP TS 36.331) only signals values that change from those used in the source cell.
  • 3GPP TS 36.331 specifies the signalling (the Protocol Data Unit content) by means of ASN.1. Fields for which delta signalling applies are defined as optional, so they may be absent, in combination with a need code of 'ON' whereby in case of absence the receiver takes no action with respect to such fields, and where applicable continues to use the existing value (and/or associated functionality).
  • explicit signalling is required to deactivate functionality associated with that field, such as for backward compatibility purposes, as applies when the target eNB does support the concerned functionality.
  • the sps-Config field 310 illustrated in FIG. 3 is absent in a RadioResourceConfigDedicated identity element (IE)
  • the UE will continue to use previously configured values. Accordingly, in order to deactivate previously active functionality, it is necessary to include the appropriate fields in a manner that is suitable to 'clear' the previously configured values.
  • the RRC protocol defined in 3GPP TS 36.331 includes different kinds of protocol extensions that may be added for later versions of the specifications, of which there are two prime categories: non-critical extensions (NCE) and critical extensions (CE).
  • NCE non-critical extensions
  • CE critical extensions
  • the non-critical extension mechanism is the primary extension mechanism, since it just adds on to the existing signalling. This, for example, means that when a message is received that includes non-critical extensions that are not comprehended by the receiver, the message may be processed as if the extensions were not present. In contrast, a message that includes critical extensions that are not comprehended is completely ignored by the receiver.
  • critical and non-critical extensions are provided in various different manners:
  • the invention seeks to mitigate, alleviate or eliminate one or more of the above mentioned disadvantages singly or in any combination. Aspects of the invention provide a target base station and a method therefor as described in the appended claims.
  • a method for configuring radio access functionality of a wireless communication unit within a wireless communication network comprising, at a radio access network entity, sending to the wireless communication unit an indication of a required radio access protocol version to which the wireless communication unit is to be reconfigured.
  • the field within the received HANDOVER REQUEST message may form a part of a HandoverPreparationInformation message contained within the HANDOVER REQUEST message.
  • the target radio access protocol version of which an indication is sent to the wireless communication unit may comprise a latest supported radio access protocol version from a subset of radio access protocol versions.
  • sending to the wireless communication unit an indication of a target radio access protocol version to which the wireless communication unit is to be configured may comprise adding the indication of the target radio access protocol within a field of a connection re-establishment message to be sent to the wireless communication unit in response to receiving a connection reestablishment request message from the wireless communication unit.
  • a computer program product comprising executable program code for configuring radio access functionality of a wireless communication unit within a wireless communication network, the executable program code operable for receiving an indication of a required radio access protocol version to which the wireless communication unit is to be reconfigured, and deactivating radio access functionality introduced in radio access protocol versions later than the indicated required radio access protocol version.
  • the method comprises sending to the wireless communication unit an indication of a required radio access protocol version to which the wireless communication unit is to be reconfigured.
  • the network entity is able to (re)configure radio access functionality that is active within the wireless communication unit in accordance with a required radio access protocol version.
  • the network entity is able to configure the wireless communication unit to deactivate radio access functionality introduced in later versions of the radio access protocol relative to that version supported by the network entity (the required version), even though the network entity does not recognise such functionality.
  • the term 'radio access protocol version' may relate to a specific release of a radio access protocol, for example REL-8 or REL-9 of the E-UTRA technical specifications, such as 3GPP TS 36.331, and/or to a specific version of a release, for example 3GPP TS 36.331 v8.7.0 for REL-8, or 3GPP TS 36.331 v9.0.0 for REL-9.
  • Possible solutions for releasing a previously configured functionality may include:
  • measConfig For other parts of the UE configuration, such as measConfig, securityConfig, switching to a default configuration is currently not supported. Moreover, for some parts of the configuration it may not be possible to support different scenarios by means of a single default. In other words, multiple default values may need to be defined.
  • the source eNB should not perform the deactivation of the functionality in parallel to the handover preparation. If the deactivation of the functionality were performed in parallel with the handover preparation, the UE might lose the radio connection before the source eNB was able to complete the deactivation of the concerned functions. In such a case, the radio access configuration in the UE would still include the unsupported functions while the configuration of the target eNB does not include these functions. Due to this mismatch, the re-establishment procedure could fail, in which case the recovery from the radio link failure would be delayed significantly.
  • Each of the radio network subsystems 420, 430 for the illustrated example comprises one or more radio network controllers (RNCs) 422, 432 operably coupled to the core network 410, with each RNC 422, 432 being further operably coupled to one or more base transceiver stations 424, 434, referred to as NodeBs in 3GPP parlance, and more specifically evolved NodeBs (eNBs) in E-UTRA parlance.
  • RNCs radio network controllers
  • eNBs evolved NodeBs
  • Each base transceiver station 424, 434 is arranged to provide radio access to the wireless communication network 400 to enable wireless communication units, such as user equipment (UE) 440, to connect thereto, for example via an air (Uu) interface 445.
  • UE user equipment
  • Uu air
  • such a source network entity radio access protocol version comprises a version earlier than or equal to that supported by the target network entity, eNB 434, it may be assumed that all currently active radio access functionality of UE 440 is supported by the target eNB 434, and as such no reconfiguration of the radio access functionality of the UE 440 is necessary.
  • the wireless communication unit radio access protocol version may comprise a latest radio access protocol version in which active functionality of the wireless communication unit is introduced.
  • the UE 440 only has active radio access functionality introduced in versions of the radio access protocol up to (and including) that wireless communication unit radio access protocol version.
  • eNB 343 it may be assumed that all currently active radio access functionality of UE 440 is supported by the target eNB 434, and as such no reconfiguration of the radio access functionality of the UE 440 is necessary.
  • the method starts at step 610 with the receipt of a handover request from a source eNB 434.
  • step 620 admission control in performed and resources are reserved within the target cell for the UE to which the handover request relates, and a connection reconfiguration message is then prepared in step 630.
  • step 640 It is then determined, in step 640, whether a source network entity radio access protocol version (VS) comprises a version later than a supported (target) radio access protocol version (VT).
  • Step 640 may additionally or alternatively comprise determining whether a wireless communication unit radio access protocol version comprises a version later than a supported radio access protocol version.
  • step 640 if it is determined that the source network entity radio access protocol version (and/or the wireless communication unit radio access protocol version) does not comprise a version later than a supported radio access protocol version, the method directly on to step 660, where a handover request acknowledgement is returned to the source eNB comprising the connection reconfiguration message to be forwarded to the UE, and the method then ends at step 670 with the establishment of a connection with the UE.
  • FIG. 8 there is illustrated an example of a simplified flowchart 800 of a method for configuring radio access functionality of a wireless communication unit (UE) within a wireless communication network according to some example embodiments of the present invention.
  • the method of FIG. 8 may be performed by signal processing logic 446 of UE 440 by way of executable program code stored in a memory element 448.
  • the source eNB 424 sends a HANDOVER REQUEST message 910 to the target eNB 434 comprising an indication of at least one of a source network entity radio access protocol version and a wireless communication unit radio access protocol version, for example within a field, illustrated as protocolVersion field 912 forming part of a HandoverPreparationInformation message 914 contained within the HANDOVER REQUEST message 910.
  • the target eNB 434 then returns a HANDOVER REQUEST ACK message 920 to the source eNB 424 comprising a connection reconfiguration message 924 containing an indication of a target radio access protocol version within a filed, illustrated as SwitchToProtocolVersion field 922.
  • a radio link failure occurs between the source eNB 424 and the UE 440 before the source eNB 424 forwards the connection reconfiguration message 924 to the UE 440.
  • the UE 440 Upon detection of the radio link failure, the UE 440 initiates a connection re-establishment procedure, whereby the UE searches for a suitable cell within which to connect.
  • the UE Upon finding a potential cell within which to connect, the UE performs an initial access procedure (not shown) and transmits a connection re-establishment request message to the eNB for that cell.
  • the UE 440 transmits a connection re-establishment request message 930 to the target eNB 434. Since the source eNB 424 had initiated handover preparations with the target eNB 434, the target eNB 434 accepts the re-establishment request and returns a connection re-establishment message 940 to the UE 440. In accordance with some example embodiments of the invention, the target eNB 434 adds an indication of the target radio access protocol within a field, illustrated as switchToProtocolVersion field 942, of the re-establishment message 940.
  • the UE 440 Upon receipt of the indication of a required radio access protocol version to which it is to be configured, which for the illustrated example embodiment is received within the connection re-establishment message 940, the UE 440 is arranged to deactivate radio access functionality introduced in radio access protocol versions later than the indicated required radio access protocol version. In this manner, radio access functionality introduced in later radio access protocol versions may be deactivated within the UE 440 without the need to explicitly identify such functionality. For the example illustrated in FIG.
  • the indication of a required radio access protocol version to which a wireless communication unit is to be reconfigured has been sent to the wireless communication unit as part of a handover procedure, or a connection re-establishment procedure following a radio link failure during a handover procedure in the case of FIG. 9 .
  • the present invention is not limited to implementation within a handover procedure or connection re-establishment procedure, but may equally be applied to any situation in which a wireless communication unit is (or may be) required to reconfigure its radio access protocol functionality.
  • FIG. 10 illustrates an example of a simplified flowchart 1000 of a method for configuring radio access functionality of a wireless communication unit according to some alternative example embodiments of the present invention.
  • the method of FIG. 10 may be performed by a network entity within the wireless communication network 400 of FIG. 4 , such as by signal processing logic 426, 436 of one of the eNBs 424, 434 by way of executable program code stored in a respective memory element 428, 438.
  • the method starts at step 1010 with receipt of an indication that a change of radio access protocol version is required for a UE.
  • a radio access network entity may receive an indication that a UE is required to 'rollback' to an earlier radio access protocol version, or simply to support a specific radio access protocol version.
  • step 1020 a reconfiguration message is prepared, and a SwitchToProtocol field is added to the reconfiguration message in step 1030.
  • the reconfiguration message is then sent to the UE at step 1040, and the method ends at step 1050.
  • FIG. 12 there is illustrated an example of an ASN.1 (Abstract Syntax Notation One) extract 1200 for signalling details for an RRCConnectionReconfiguration message comprising a switchToProtocolVersion field 1222, such as may be used within the HANDOVER REQUEST ACK message 520 within message sequence 500 of FIG. 5 .

  • the wireless communication unit functionality 1400 further comprises a measurement unit 1420, arranged to perform the measurements that are configured by the radio access network, a security unit 1430, arranged to perform the integrity protection for signalling radio bearers (SRBs), the ciphering for radio bearers as well as the associated key derivations, and a radio access unit 1440, arranged to handle the layer 1 and layer 2 functionality of the radio access protocols.

  • Radio resource control unit 1550 is arranged to handle configuration of the layer-1 and layer-2 functionality of the radio access protocols.
  • a possible disadvantage of using a need OR is that if the concerned functional extension upon handover is to be continued, it needs to be signalled thereby increasing the size of the handover message. This increase can however easily be avoided by having another optionality bit with need ON, one level below. In such a case 2 bits would need to be signalled to continue the functional extension. This approach is illustrated by an example, as shown in Fig. 17 .
